Be it known that L'AMos F. DIXON, a citizen of the -United States, residing .at Newark, in thecounty of Essex and State of New Jersey, have invented a certain new and useful Improvement in Paper-Feed- -Control1ing Systems, of which the follow ing is a full, clear, concise, and exact description. a

This invention relates to paper feed controlling systems and'is particularly adapted for use in page printing telegraph systems,

although obviously not exclusively limited to such use.

One of the objects of this invention is 'to provide an automatic, paper feeding and measuring device wherein it is unnecessary to employ perforated or otherwise previously prepared'sheets 'of paper to effect the control. 7 a I Another object is to provide means whereby message blanks "may beautomatically 'prepared'from a continuous sheet of paper without 4 the employment of tear lines therein.

Specification of Letters Patent.

v magnet 34.

To'the above ends,.an automatic paper feeding device is provided in' combination with means, influenced by the margin of the paper, for effecting control over the feeding-operation and shearing means for automatically severing the sheet of paper into separate message blanks.

The above and other objects of this invention 'will befully set forth in the fol- .lowing description and claims, and 'will be more readily understood by reference to the accompanying drawing, in which the system of connections and the apparatus are shown diagrammatically.

A continuoussheet of paper the'messages' are to be printed, passes upward between a type wheel 11 and a printing platen 12 ofany suitable construction,

"The paper after being printed upon passes into a suitable guide-way formed by curved walls 15 and 16, the upward movement-being effected by a feed roller 20 and a pres-' sure roller 21. Feed roller 20 is provided with a ratchet 22, the teeth of" which are adapted tobe engaged by a pawl-23. Pawl 23' is pivotally carried by a spring-tensioned armature 25, of a feed magnet 26. Preferably, feed magnet '26, through the agency of armature .25, pawl 23, ratchet 22 and wheels 20 and 21, may be used for the line- 10, on which.

feed magnet 26 from grounded battery 59.

to-line feed required by the printer in addition to the message blank feed, to be presently described.

In order to separate each" message blank from the remaining sheet of paper, the sheet 10 upon entering between walls 15 and passes a paper shearing device 30. This device comprises a knife 31, die block 32, actuating armature lever 33 and shearing lVhen a message has been printed by the type 'wheel 11 and printing platen 12, anysuitable apparatus or circuit arrangement may be utilized to eflectthe momentary closing of contacts 35. This completes a circuit from grounded battery- 40, contacts 35, conductor 41 and feed con trol relay 42 to ground 43. Y Feed control relay 42 thereupon attracts both its armatures 44 and 45. Armature 44 completes a hold ing circuit for relay 42 from ground 43 by way of conductor 50 and back contact and armature of clear-out relay 52 to grounded battery 58. Armature 45' completes a circuit from ground 48, armature 45, front contact 1 54, resistance 55, conductors 56 and 57 interrupting relay.'58 to grounded battery 59. Interrupting relay 58 attracts its armature 65 providing an energizing. circuit for the Feed magnet 26 now becomes active pulling up both its armatures 25 and66. Armature 25, as previously explained, causes the advancement of the paper sheet 10. Armature 66 completes a shunt about interrupting relay 58 by means of conductor 68, front contact and armature 66 and battery 67. Interrupting relay 58 thereupon becomes deenergized, releases its armature 6.5 and consequently opens the energizing circuit for feed magnet 26. Armature 25 thereof isreturned by its spring ready to engage the next tooth of ratchet 22 while armature 66, returning, removes the shunt from around interrupting relay 58, which thereupon again becomes energized' and the cycle of operations just outlined is reproduced. The paper 10 continues to be automatically fed step-by-step up between the walls 15 and 16 until the proper length of a message blank is reached, when the advance edge thereof engages a contact lever 70 moving it against the tension of its spring71, into engagement with a contact 72.

The engagement of contacts 70 and 72 closesanenergizing circuit from grounded battery 53, clear-out relay 52, conductor 7 3, contacts 70 and 72 conductor 74, and shearing magnet 34 to ground. Shearing magnet 34 attracts its lever armature 33 and forces the knife 31 through the paper 10, into the. die block 32, severing the prepared message from the remaining sheet. The energization of clear-out relay opens the previously traced holding circuit for the control relay 42 and with the removal of the prepared blank to allow the disengagement of contacts 70 and 72, all of the apparatus is again at normal.

\Vhat is claimed is;

1. A paper feed controlling system comprising feeding mechanism, an automatically acting electromechanical system for operating said mechanism, means to initiate the action of said system, and .means controlled by the advancing edge of the paper for influencing said system to stop the feeding action. I

2. A paper feed controlling system comprising electromagnetic means for feeding a sheet of paper step-by-step, an interrupter relay cooperating'with said electromagnetic means to establish automatic feeding action, means for initiating the feeding action, contacts adapted to be controlled by the advancing edge of a sheet of paper, and means controlled thereby for stopping the feeding action.

3 A paper feed controlling system comprising electromagnetic means for feeding a sheet of paper step-bystep, electromagnetic paper shearing means, an interrupter relay cooperating With'said feeding means to establish and maintain automatic feeding action, means for initiating the feeding action, contacts adapted to be controlled by the edge of a sheet of paper, means controlled thereby for arresting said feeding action, and means also controlled thereby for causing the action of said shearing means. 1
